		Verapamil HCl is a calcium ion influx inhibitor (slow channel blocker or calcium ion antagonist).
		Verapamil is administered as a racemic mixture of the R and S enantiomers.
		Verapamil HCl is an almost white, crystalline powder, practically free of odor, with a bitter taste.

	Verapamil
		Calan (verapamil HCl) is a calcium ion influx inhibitor (slow-channel blocker or calcium ion antagonist) used to treat angina (chest pain) or high blood pressure.
		Verapamil's effectiveness in vasospastic angina is due to a decrease in coronary vascular tone.
		Verapamil is a calcium ion influx inhibitor (slowchannel blocker or calcium ion antagonist) that exerts its pharmacologic effects by modulating the influx of ionic calcium across the cell membrane of the arterial smooth muscle as well as in conductile and contractile myocardial cells.

	Verapamil
		Verapamil is a calcium channel blocker used principally for its effects in cardiac tissue.
		Verapamil should not be used in animals with known hypersensitivity or allergy to the drug.
		Verapamil should also be used with caution in animals with hepatic dysfunction as animals with pre-existing hepatic dysfunction may have an increased risk of toxicity due to delayed metabolism of the drug and subsequent accumulation.

		Thus, verapamil is useful in treating and preventing chest pain (angina) resulting from spasm (contraction) of the coronary arteries that reduces the flow of blood to the heart.
		Insufficient oxygen-carrying blood may be a result of blockage of blood flow in the coronary arteries due to coronary artery disease or spasm, or an increase in physical exertion that increases the workload of the heart and the demand by the heart for oxygen.
		Verapamil slows electrical conduction of the electrical impulses through the heart and has been used to in treat abnormally fast heart rhythms such as atrial fibrillation, and in the prevention of recurrent episodes of rapid heart rhythm originating from the atria.

	Verapamil
		Verapamil can be tried as an initial agent in those patients in whom the use of diuretics and/or beta-blockers is contraindicated or in patients with medical conditions in which these drugs frequently cause serious adverse effects.
		Because verapamil is extensively metabolized by the liver, it should be administered cautiously to patients with impaired hepatic function, since the elimination half-life of verapamil in these patients is prolonged 4-fold (from 3.7 to 14.2 hours).
		Verapamil is not recommended for use in pregnant women unless the potential benefits outweigh potential risks to mother and fetus.

	Verapamil- AFF
		During episodes of atrial fibrillation, or in chronic atrial fibrillation, one of the goals of treatment is often to slow and regularize the ventricular response to rapid atrial activity.
		Verapamil is quite effective at slowing the ventricular response to fibrillation both at rest and during exercise.
		One of the actions of verapamil is to lower blood pressure, so patients whose blood pressure is already normal or low-normal may have side effects from low blood pressure such as dizziness or lightheadedness, particularly when rising from a seated or lying position.

	Calan (verapamil) prescription
		Verapamil is primarily prescribed to treat: angina (Prinzmetal's variant angina) not caused by exertion, angina caused by exertion in those who do not respond to treatment with beta blockers or nitrates, arrhythmias (irregular heartbeat), rapid heartbeat caused by atrial fibrillation, tachycardia, and high blood pressure (hypertension).
		Other uses for which Verapamil is acceptable include: cluster headache reduction, halt the progression of artherosclerosis, hypertrophic cardiomyopathy, prevention of abnormal heart rhythm after surgery, reduces stuttering in some cases, retard keloid formation, secondary therapy for panic attack symptoms, or as secondary therapy for Tourette's syndrome.

	Calcium channel blockers for bipolar disorder
		Verapamil has been around a long time, and as a result there are multiple generics around (thus no trade name above).
		As a result of this "mixed" evidence, interest in verapamil has been very limited (in addition, because it is available in multiple generics, there is no manufacturer willing to pump money into research and advertising for this medication, so it "looks" less attractive than it really is).
		When verapamil was blindly substituted for nimodipine, two BP patients failed to maintain improvement but responded again to nimodipine and remained well with a blind transition to another dihydropyridine L-type calcium channel blocker (CCB), isradipine.
